It resides nearby mountain creeks, in Sichuan (Emei, Hongya) only, where the sea level is from 1050 to 1800m.

Life History, Abundance, Activity, and Special Behaviors
Adults live on land, and are active in late April. They squat beneath rocks in the creek during the day and beneath rocks near the creek at night. The breeding season is in June. Females lay about 183 eggs in a circular patch. After breeding, they reside in dark, moist areas in the forest. Tadpoles are active during the summer along submerged rocks, looking for moss and detritus to eat.
